Errata for paper and PhD thesis Surface reconstruction from unorganized points

In the SIGGRAPH 1992 paper, on page 74, the third line of the signed distance function definition should read:
   z = p - ((p - o_i) · n_i) n_i
instead of
   z = o_i - ((p - o_i) · n_i) n_i

The same correction also applies to the signed distance function definition on page 28 of my PhD thesis.
